I suppose you could try using ReadDirectoryChangesW... as for sample source, you could check out the Folder Monitor that comes with RxLib.

In NT based systems (NT4, 2000, XP) you can use ReadDirectoryChangesW, unfortunately there's nothing comparable in win9x based systems. You can use FindFirstFileNotification, but you'll only be notified that *something* changed in the directory you're watching. If that is good enough for you: Fine.

There are some undocumented functions, which work also in win9x. However, those functions are not really reliable. They work most of the time, but not always. I've implemented this kind of stuff in my madShell package (free for non-commercial usage). Look here for more infos:
